The party still isn’t over for Sean “Diddy” Combs, who threw a lavish bash to celebrate his 40th birthday last week. A few nights later, Diddy and Jay-Z checked out CV Lounge’s private couples room, which owner Matthew Isaacs rents out for $5,000 a night. The space is outfitted with padded walls and a couch, eight ounces of beluga caviar and a magnum of champagne. There don’t seem to be specific rules on what can go on in there, but sources say Diddy and Jay-Z “relaxed and shared a drink while listening to the music.”
